Preheat the oven to 350 degrees.
In a medium bowl combine oats, flaxseed meal, cinnamon, nutmeg, baking powder, and salt. Set aside.
In a separate bowl, whisk eggs together with honey, oil, apple sauce, milk, and vanilla until combined.
Pour the dry ingredients into the wet ingredients. Mix well.
Stir in almond butter, pecans, and diced apple. Mix well, making sure almond butter is incorporated into the batter.
Line a muffin pan with baking cups or thoroughly spray muffin pan with non-stick cooking spray. Divide the oatmeal mixture among muffin cups, filling each cup to the top.
